[原创]onsemi NCN26010 10Mbps工业以太网MAC＋PHY控制器解决方案

onsemi 公司的NCN26010是IEEE 802.3cg兼容以太网收发器,包括媒体接入控制器(MAC),PLCA协调子层(RS)和设计用于工业多点以太网的10BASE−T1S PHY.提供需要在单非屏蔽双绞线上发送和接收数据所需物理层功能.NCN26010和主MCU通过开放行业联盟MACPHY SPI协议进行通信.器件支持工作共享媒体(多点)网络段,至少25米单双绞线(UTP/STP)连接. NCN26010提供从模式的串行外设接口(SPI),允许低引脚数连接到现成的MCU和其它SPI主器件.器件提供半双工模式的共享总线速度10Mbps.器件和 10BASE−T1S – IEEE 802.3cg 兼容,3.3V电源. 采用4 mm x 4 mm QFN 32 / TQFP32 (5 mm x 5 mm)封装.主要用在工业自动化,传感器接口,家庭/建筑物控制,安全和现场仪表.本文介绍了ncn26010主要特性,框图, 基本应用框图及其所推荐外接元件, 10BASE-T1S 电源和适配器板的评估板NCN26010BMNEVB主要特性,框图,电路图和材料清单.

The NCN26010 device is an IEEE 802.3cg compliant Ethernet Transceiver including a Media Access Controller (MAC), a PLCA Reconciliation Sublayer (RS) and a 10BASE−T1S PHY designed for industrial multi−drop Ethernet. It provides all physical layer functions needed to transmit and receive data over a single unshielded twisted pair. NCN26010 communicates to host MCUs via the Open Alliance MACPHY SPI protocol.

The NCN26010 is a 10BASE−T1S Physical Layer Transceiver as specified in IEEE 802.3cg with integrated Media Access Controller (MAC) and PLCA Reconciliation Sublayer.
